Structural Engineering Software for Industrial and Plant Structures

The structural engineering programs are ideal for structural design and analysis of industrial constructions such as chemical plants, production halls, containers, piping systems, large filters, and more.

RSTAB allows for the design of member structures and RFEM for additional plate, wall, shell, and solid elements.

Structural engineering FEA software RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to beam, frame, or truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.

Critical load factors and the corresponding mode shapes of any structure can be efficiently determined in RFEM and RSTAB using the RF-STABILITY or RSBUCK add-on module (linear eigenvalue solver or nonlinear analysis).

This article explains how to determine loads on the basis of the internal force situations defined in the RF-/STEEL Warping Torsion extension of the RF-/STEEL EC3 add-on module. Since this new program allows you to also analyze extracted chain-like beam structures in addition to entire chain-like beam structures, it is necessary to determine the loads of the partial structure separately. For this, a special transformation function has been developed, which determines new loads of all partial structures (depending on the internal forces calculated in RFEM/RSTAB) according to each load situation for geometrically nonlinear warping torsion analysis with seven degrees of freedom.
